聚醯胺：市場佔有率分析、產業趨勢與統計、成長預測（2026-2031）

2025 年聚醯胺市場價值為 509 萬噸，預計從 2026 年的 531 萬噸成長到 2031 年的 659 萬噸，在預測期（2026-2031 年）內複合年成長率為 4.41%。

這一成長趨勢得益於汽車輕量化法規、電動車 (EV) 產量的快速成長以及 5G 電子產品中高溫聚合物的加速應用。聚醯胺，尤其是 PA6 和 PA66，正不斷取代金屬，應用於引擎室零件、線束和電池組件，從而在減輕重量的同時，還能承受約 180°C 的持續高溫。包裝應用領域也呈現成長勢頭，食品保鮮領域對阻隔薄膜的需求日益成長，而生物基聚醯胺則滿足了品牌所有者的永續性目標。供應安全仍然是戰略重點。 2024 年原物料價格的波動擠壓了利潤空間，己二腈供不應求限制了 PA 66 的生產，這使得擁有整合供應鏈的製造商獲得了市場佔有率。

全球聚醯胺市場趨勢與洞察

輕量化汽車應用領域需求強勁

為了滿足日益嚴格的燃油經濟性和排放氣體法規，汽車製造商正擴大採用PA6和PA66。電氣化進一步加速了這一趨勢，因為每減輕一公斤重量都能在不犧牲車內空間的前提下增加車輛續航里程。歐洲汽車製造商報告稱，將動力傳動系統部件從金屬部件轉向玻璃纖維增強聚醯胺，重量減輕了15-20%。對於引擎室零件而言，聚醯胺在高達180°C的溫度下仍保持穩定，其性能優勢是傳統聚丙烯無法比擬的。隨著全球乘用車產量的復甦和電動車普及速度的加快，整車製造商的籌資策略正在確保樹脂的長期供應，鞏固了聚醯胺市場最具影響力的成長支柱。

由於電氣化，對線束和溫度控管的需求迅速成長。

電動車架構需要緊湊的線束和能夠承受高電壓和高熱流的堅固電池外殼。 PA12 和耐熱 PA66 具有優異的耐電解性和低溫柔柔軟性，可實現更薄的壁厚和更小的彎曲半徑。特斯拉在其 Model Y 的線束網路中採用了特種聚醯胺，在保持介電性能的同時減輕了線束重量。電動車的快速普及加速了這一需求，亞洲、歐洲和北美的新電池和線束工廠紛紛運作。計劃從早期階段就開始指定使用高性能聚醯胺材料。

己內醯胺和己二酸原料價格波動

2024年，與原油價格掛鉤的己內醯胺價格大幅上漲，擠壓了未避險的聚合物工廠的轉換利潤率。依賴亞洲進口的歐洲和北美生產商面臨不斷擴大的到岸成本價差，壓縮了BASF聚醯胺部門的盈利。限制一氧化氧化亞氮的己二酸法規排放收緊了供應，加劇了成本波動，並抑制了長期合約的簽訂，尤其是對於中小加工商而言。

細分市場分析

2025年，PA 6佔據了聚醯胺市場58.12%的佔有率。其均衡的性能和寬廣的加工窗口使其適用於大規模生產的汽車零件和工業齒輪。區域性混煉廠商重視其與玻璃纖維和阻燃劑的相容性，並維持成熟的供應鏈。然而，隨著成熟應用接近飽和，其成長速度正在放緩。 PA66預計到2031年將以4.74%的複合年成長率（CAGR）保持最高水平，這主要得益於對熱變形溫度超過200°C的引擎艙部件、電池冷卻板和5G連接器的需求。儘管己二酸丁腈橡膠的供應受到限制，但原始設備製造商（OEM）對設計的執著將保障需求並維持其價格溢價。

醯胺纖維和PPA（聚亞苯丙烯）等特殊叢集佔據了小眾但盈利的市場需求。醯胺纖維在航太蜂窩、防彈材料和高抗張強度繩索等領域的應用利潤率很高，但產量仍有限。 PPA產品已滲透到渦輪增壓器空氣冷卻器端蓋和電動動力傳動系統模組中，並享有兩位數的價格溢價。為了因應特種纖維市場的擴張，BASF等傳統PA6供應商推出了「Ultramid Advanced」系列產品，該系列產品具有更高的玻璃化轉變溫度和耐化學性。這模糊了產品類別之間的界限，迫使買家評估特定應用的性能，而不是通用樹脂系列。聚醯胺市場佔有率的成長取決於成本、供應安全和技術利潤之間的平衡。 OEM材料選擇委員會越來越關注整體擁有成本（TCO），權衡輕量化和小型化帶來的好處與原物料價格波動帶來的風險。因此，PA6 在對成本敏感的組件領域保持主導地位，而 PA66 和 PPA 在對工作溫度和化學應力要求較高的先進應用中正在取得進展。

本聚醯胺市場報告按樹脂子類型（PA6、PA66、芳香聚醯胺、PPA）、終端用戶產業（汽車、電氣電子、航太、工業機械、建築施工、包裝及其他終端用戶產業）和地區（亞太、北美、歐洲、南美、中東和非洲）進行細分。市場預測以數量（噸）和價值（美元）為單位。

第7章 市場機會與未來展望

第8章：執行長面臨的關鍵策略挑戰

The Polyamides Market was valued at 5.09 million tons in 2025 and estimated to grow from 5.31 million tons in 2026 to reach 6.59 million tons by 2031, at a CAGR of 4.41% during the forecast period (2026-2031).

This growth trajectory is underpinned by automotive lightweighting mandates, the rapid scaling of electric vehicle (EV) production, and the accelerating adoption of high-temperature polymers in 5G electronics. Polyamide grades, notably PA 6 and PA 66, continue to displace metals in under-hood parts, wire harnesses, and battery components because they provide weight savings while withstanding sustained temperatures near 180 °C. Packaging applications are also gaining momentum as barrier-film requirements rise in food preservation, while bio-based polyamides answer brand-owner sustainability targets. Supply security remains a strategic priority: feedstock price swings in 2024 squeezed margins, and adiponitrile bottlenecks constrained PA 66 output, prompting producers with integrated chains to capture share.

Global Polyamides Market Trends and Insights

Robust Demand from Lightweight Automotive Applications

Automakers are increasingly selecting PA 6 and PA 66 to comply with stringent fuel-efficiency and emission regulations. Electrification intensifies this trend because every kilogram of mass eliminated extends driving range without sacrificing cabin space. European OEMs report 15-20% weight cuts in powertrain parts after shifting from metals to glass-fiber-reinforced polyamides. Under-hood components benefit from polyamides' stability up to 180 °C, providing performance margins that conventional polypropylene cannot achieve. As global passenger-vehicle output rebounds and EV penetration accelerates, OEM sourcing strategies lock in long-term resin volumes, anchoring the most influential growth pillar for the polyamides market.

Surge in E-Mobility Wire Harness and Thermal Management Needs

EV architecture demands compact wiring looms and robust battery housings that can handle higher voltages and heat flux. PA 12 and heat-stabilized PA 66 exhibit superior electrolyte resistance and low-temperature flexibility, enabling slim wall thickness and tighter bend radii. Tesla introduced specialized polyamides into the Model Y wiring networks, reducing harness mass while maintaining dielectric properties. Rapid EV scaling makes this driver immediate, with Asia, Europe, and North America commissioning greenfield battery and harness plants that specify high-performance polyamide grades from project inception.

Volatility in Caprolactam and Adipic Acid Feedstock Prices

Crude-linked caprolactam quotations spiked in 2024, eroding conversion margins at polymer plants that lack hedged sourcing. European and North American producers, who are dependent on Asian imports, faced wider landed-cost spreads, compressing profitability at BASF's polyamides division. Adipic-acid regulations restricting nitrous oxide emissions further squeezed the supply, amplifying cost volatility and deterring long-term contracts, especially for smaller processors.

Other drivers and restraints analyzed in the detailed report include:

1. Growth in 5G Electronics Requiring High-Temperature Polymers
2. Shift Toward Bio-Based Polyamides in Consumer Brands
3. Persistent Supply-Demand Imbalance in PA 66 Base Polymer

Segment Analysis

PA 6 accounted for 58.12% of the polyamides market size in 2025, as its balanced property set and wide processing window favor large-volume automotive components and industrial gears. Regional compounders appreciate its compatibility with glass fibers and flame retardants, sustaining entrenched supply chains. Yet growth moderates as mature applications saturate. PA 66 recorded the leading 4.74% CAGR through 2031, propelled by under-hood parts, battery cooling plates, and 5G connectors where heat deflection temperatures exceed 200 °C. Despite adiponitrile bottlenecks, OEM design lock-in protects demand, and price premiums remain defensible.

The specialty cluster-aramids and PPA-addresses niche but lucrative needs. Aramid fiber usage in aerospace honeycomb, ballistic protection, and high-tension cords yields strong margins; however, volumes remain modest. PPA grades penetrate turbocharger air-cooler end tanks and electric powertrain modules, commanding double-digit price premiums. Traditional PA 6 suppliers, such as BASF, introduced Ultramid Advanced lines that elevate glass-transition temperatures and chemical resistance to counter specialty incursions. This blurs category boundaries, nudging buyers to evaluate performance on an application-specific basis rather than generic resin families. Polyamides market share gains hinge on balancing cost, availability, and technical headroom. OEM material-selection committees are increasingly running total-cost-of-ownership scenarios, weighing feedstock volatility against the advantages of lightweighting or miniaturization. As such, PA 6 retains leadership in cost-critical parts, whereas PA 66 and PPA capture frontier applications where operating temperatures or chemical exposure escalate.

The Polyamides Market Report is Segmented by Sub-Resin Type (PA 6, PA 66, Aramid, and PPA), End-User Industry (Automotive, Electrical and Electronics, Aerospace, Industrial and Machinery, Building and Construction, Packaging, and Other End-User Industries), and Geography (Asia-Pacific, North America, Europe, South America, and Middle-East and Africa). Market Forecasts are Provided in Terms of Volume (Tons) and Value (USD)

Geography Analysis

The Asia-Pacific region held a 50.88% share of the polyamides market in 2025 and is projected to grow at a 4.89% CAGR through 2031. China's growing EV output will magnify demand for wire harness resins, while India's electronics push is expected to add volumes in high-temperature grades. Japan supplies precision compounding and aromatic polyamides for hybrid powertrains, and South Korea deploys PPA in 5G modules sold worldwide. Although feedstock self-sufficiency is improving, the caprolactam supply concentration makes the region vulnerable to crude oil price fluctuations. Nations such as Malaysia and Thailand target downstream investment incentives to diversify production footprints, attracting second-wave processors seeking China-plus-one strategies.

United States automakers incorporate lightweighting polymers aggressively, and aerospace primes specify 3D-printing powders for cabin and engine-bay parts. Ascend's vertically integrated PA 66 chain shields domestic buyers from some adiponitrile shortages, but capacity constraints still ripple across specialist grades. Mexico's vehicle assembly uptrend taps cost-efficient PA 6 from regional compounders, while Canada's aerospace supply base experiments with high-performance aramids. Europe underscores circularity. Germany's premium OEMs are locking in bio-content or recycled polyamides despite higher costs, thereby embedding sustainability into their supplier scorecards. France's aviation segment drives certification of additive-manufacturing grades, and Italy's machinery cluster maintains reliable demand for engineered wear parts. The European Chemicals Agency continues to expand scrutiny of additives under REACH, rewarding producers with robust regulatory dossiers. Brexit-era U.K. manufacturing targets high-margin specialty compounds to offset volume leakage. South America, the Middle East, and Africa collectively account for smaller shares, yet deliver upside through automotive localization and infrastructure expansion. Brazil's flexible-packaging converters are exploring polyamide multilayers for export-oriented agrifood shipments, whereas Gulf Cooperation Council countries are leveraging low-cost feedstock to attract resin investments.
